I'm helping out a friend with setting up a network. He currently has his cable modem & connection coming in the basement, and connecting to a 5 port Linksys wired router. Out of the 5 wired ports, one is going straight up to an office directly above, one is running up to the 2nd floor, one is going to the kitchen, and another is going to a game room. The other ports are not used. The connection going to the kitchen is being used by two laptops, but they take turns plugging the line into their machines. What he would like to do is have me install & setup an Apple Airport Extreme (current 802.11N model) with the dedicated line coming to the Kitchen, so they can have wireless in the Kitchen/Dining Room/Deck area. Barring anything I'm overlooking, would this be feasible? Any potential conflicts since this is a wireless router being plugged into a wired router? The section of the basement where the line comes in is on the other end of the house, so they were using wired setups until this point. The walls have swiss cheese type constructions made of metal sheets. It's hard to explain, but wireless signals tend to die quickly, so getting access in the Kitchen/Dining Room and the close outside deck would be enough. The rest of the building would stay on wired connections. Machines: -- Office: IBM Thinkpad (Pentium III) using wired connection. (possibly upgrading to a Macbook soon) -- Gameroom: Laptop using Vista Ultimate -- 2nd Floor (nothing connected, used as an extra wired connection) -- Kitchen: PowerBook G4 with 802.11G and iBook G4 with 802.11G. The iBook is OS 10.4.10, and the PowerBook is OS10.3.9. Internet: -- Cable Internet 6mbps How about multiple networks? For example an Airport Extreme on the 1st floor, another on the second floor, etc. ? The building is 4 stories tall, and they may be interested in expanding the network further. Thanks!!
